SIGPAUSE(3) NetBSD Library Functions Manual SIGPAUSE(3)
NAMEsigpause -- atomically release blocked signals and wait for interrupt
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS#include <signal.h>intsigpause(int sigmask);
DESCRIPTIONThis interface is made obsolete by sigsuspend(2).sigpause() assigns sigmask to the set of masked signals and then waits
for a signal to arrive; on return the set of masked signals is restored.
sigmask is usually 0 to indicate that no signals are to be blocked.
sigpause() always terminates by being interrupted, returning -1 with
errno set to EINTR.
